Paul: What are you doing at the moment?
Anna: I'm reading an email from Emma. She's in Australia.
Paul: Is she having a good time?
Anna: Yes, she says it's fantastic. She goes swimming every day.
Paul: Listen! What's that?
Anna: It sounds like a mosquito.
Paul: Well, it isn't a mosquito.
Anna: Look. It's yellow and black. It looks like a wasp.
Anna: Maybe it's a bee.
Paul: That's OK, then.
